Older adults who face systemic health issues and lack adequate social support are at risk for oral health deterioration. How rapidly such changes take place depends on the severity of their medical condition and their ability to access oral health services in a timely manner. The management of dental caries and periodontal disease in this cohort is made complex by the interaction of local and host factors such as the presence of dry mouth, involvement of root surfaces, and altered wound healing.

Introduction With the advent of fixed- and variable-loop suspensory fixation devices for arthroscopic anterior cruciate ligament (ACL) reconstruction, a maximum number of grafts can be placed within the femoral tunnel. Although several biomechanical studies have been conducted comparing these two devices, only a few comparative clinical studies are available. This study was conducted to compare the functional outcomes of arthroscopic ACL reconstruction using fixed-loop devices with those of variable-loop devices by determining their effect on graft laxity clinical assessment and patient-reported outcome scores.

Little is known about the spin-flip diffusion length l_{sf}, one of the most important material parameters in the field of spintronics. We use a density-functional-theory based scattering approach to determine values of l_{sf} that result from electron-phonon scattering as a function of temperature for all 5d transition metal elements. l_{sf} does not decrease monotonically with the atomic number Z but is found to be inversely proportional to the density of states at the Fermi level.

The coronavirus disease 2019 (COVID-19) pandemic presented formidable challenges in our ability to impart in-person extra-mural clinical training, including the Geriatric and Special Needs Program, to a group of 20 fourth-year dental students. A new course delivery format was developed wherein students used a validated Rapid Oral Health Deterioration (ROHD) risk assessment tool to critically appraise clinical case information relating to a young adult with special needs. In the alternative virtual educational approach that was created, students applied an interprofessional practice concept leading to patient treatment planning outcomes.

It is mandatory for every clinician to have a thorough knowledge about the normal internal anatomy of teeth; equally important is the awareness about variations in internal anatomy that could be seen with different teeth. The outcome of a root canal therapy depends significantly on the clinician's awareness about root canal anatomy, followed by their clinical skills. Literature states that the permanent maxillary first molar shows a wide variation in the number of canals particularly with respect to the mesiobuccal root.

Taurodontism is a dental anomaly caused due to the failure of Hertwig's epithelial sheath to invaginate at the proper horizontal level. A huge pulp chamber, displacement of the pulpal floor apically, and no constriction at the level of the cementoenamel junction are the key features representing a taurodontic tooth. This condition is most commonly associated with permanent molars.

Background: Macrophage (Ma) vectorization of chemotherapeutic drugs has the advantage for cancer therapy in that it can actively target and maintain an elevated concentration of drugs at the tumor site, preventing their spread into healthy tissue. A potential drawback is the inability to deliver a sufficient number of drug-loaded Ma into the tumor, thus limiting the amount of active drug delivered. This study examined the ability of photochemical internalization (PCI) to enhance the efficacy of released drug by Ma transport.

Although mitochondrial transcription factor A (TFAM) is a protective component of mitochondrial DNA and a regulator of calcium and reactive oxygen species (ROS) production, the mechanism remains unclear. In heart failure, TFAM is significantly decreased and cardiomyocyte instability ensues. TFAM inhibits nuclear factor of activated T cells (NFAT), which reduces ROS production; additionally, TFAM transcriptionally activates SERCA2a to decrease free calcium.

Introduction: Gene-directed enzyme prodrug therapy (GDEPT) employing the cytosine deaminase (CD) gene, which encodes an enzyme that converts the nontoxic agent 5-fluorocytosine (5-FC) into the chemotherapeutic drug 5-fluorouracil (5-FU), has shown promise both in experimental animals and in clinical trials. Nevertheless, with the transfection systems available presently the percentage of tumor cells incorporating the desired gene is usually too low for successful therapy. We have examined the ability of photodynamic therapy (PDT) to enhance the efficacy of the metabolites, converted from 5-FC by CD gene transfected rat glioma cells.

Photochemical internalization (PCI) is a technique that uses the photochemical properties of photodynamic therapy (PDT) for the enhanced delivery of endolysosomal-trapped macromolecules into the cell cytoplasm. The released agent can therefore exert its full biological activity, in contrast to being degraded by lysosomal hydrolases. Activation of photosensitizers via ultrasound (US), called sonodynamic therapy (SDT), has been proposed as an alternative to light-activated PDT for the treatment of cancerous tumors.
